摘要

单胎妊娠对婴儿健康有不良影响吗?这是一个具有挑战性的研究问题，因为在怀孕期间同居存在选择。我们利用准自然变化的单胎从受孕到出生的时刻，在韩国的婚龄法律的改革产生的。韩国的出生证明数据是独一无二的。他们除了提供合法的婚姻状况外，还提供同居状况的信息。同居开始日期使我们能够确定怀孕期间同居的强度。我们发现在怀孕期间同居或合法婚姻对生育结果没有显著影响。

Does single pregnancy hurt birth outcomes among young mothers?

Abstract Does single pregnancy adversely affect infant health? This is a challenging research question because there is selection in coresidence during pregnancy. We exploit quasi-natural variation in single pregnancy from the moment of conception to birth, arising from the reform of the marriageable age laws in Korea. The Korean birth certificate data are unique. They provide the information about the coresidence status in addition to the legal marital status. The coresidence start date allows us to identify the intensity of coresidence during pregnancy. We find that coresidence or legal marriage during pregnancy does not significantly affect birth outcomes.

期刊介绍： Demographic variables such as fertility, mortality, migration and family structures notably respond to economic incentives and in turn affect the economic development of societies. Journal of Demographic Economics welcomes both empirical and theoretical papers on issues relevant to Demographic Economics with a preference for combining abstract economic or demographic models together with data to highlight major mechanisms. The journal was first published in 1929 as Bulletin de l’Institut des Sciences Economiques. It later became known as Louvain Economic Review, and continued till 2014 to publish under this title. In 2015, it moved to Cambridge University Press, increased its international character and changed its focus exclusively to demographic economics.
